Tom WILLIAM; oniafiirsvrrnnnflas 1 no'rnn srannnm ToaZZ whom it may concern;

Be'it knownthat .I, ToM WniLmMs, a citizen of the United States, residing at Marysville, in the county of Marshalland State of Kansas, have invented certain new. and I useful Improvements in Rotary Spaders, of

' which the followingis a specification. L

Thisinvention relates to rotary spaders and has more especial reference to improvements in thetypes' of CllltlYfitOI'SfihOVZIlfbIld claimed in my co-pendingU. S. application Serial No. 73,145.-

The invention has for its";dominant eat to provide a rotary spader having novelly mounted cultivating. spades, the spades be 7 ing mounted: in a niannertoicanse engagement of the same with" the soil,,upon rota:

tion of the drum, and to allovvemovement of the. drum thereover in order that the same will bedisengaged from the soil, thereby properly 'spading or turning the soil and preventing the abnormal straining [of the spades or drum. e Another and equally important objectof the invention is to providethe spade with spring buflinu means whereby all shockincident to the re ative adjustment of the, spades previous to their engagement withthe soll will be absorbed and the said spadesproperly spacedp.

The foregoing together with additional advantageous details and, arrangementof parts of the preferred embodiment of in connection with the accompanying drawings forming partthereoh'wherein said embodiment of the invention is'illustrated for the purpose of facilitating a full understanding of the present improvements.

In the drawings Figure 1 is a side elevation of the im-.

proved rotary spader showing 'the same mounted upon the drive axle of a motor driven vehicle; and

Fig. 2 is a rear elevationof one of the spades showing the manner in which the" same is secured to the drum, it being noted that the drum is fragmentarily shown in section. v I

Similar characters of reference refer to similar parts throughout the several views of thedrawings.

Having more particular reference to the drawings, M indicates the motor driven ve-. hicle to which the improved spader 1s ate 1 Spe'cification of Iietterslatent.

Mounted on one end of the drive axle of the motolpvehiclelM is a drum 1 serving as means'for carrying the spades, presently re 7 ferred to';

. A' plurality ;of

.vvhich rivets are in turnpassedthrongh the 'spading elements 2, U-shaped bolts. 6 are also passed through thespading elements 2 i "and about the intermediate portions ofthe l-shaped arms .3, thereby securely fastening the s pad ng'gelementsto the said rms In this connection, it is to be 'noted that the intermediateportions of the'U-shaped arms Bare bentfthus, arranging-the outer ends of the sameat angles to the inner ends or portions thereof. a

.' Bufi'er elements comprising spring arms-7 i I having certain ends curved upon themselves .as at 8 and the remaining ends bent atsubstantiallyright angles as at 9 and secured to the various spading elements 2 by'm'eans W v of bolts orrivets 10 and U-shaped clips 11 .servea's means for maintaining the spading invention will be clear from the specific def scription hereinafter contained, when readelements 2 in proper spaced relation in order that the same Wlll be properly engaged with the soil; also, absorbing theshock incident to the relative adjustment of the spading "elements 2 and during their movement through the soil.

From the foregoing it'will be readily I understood that the spading elements 2 due to their connection with the drum 1 will be caused to engage the soil over which the motor driven vehicle M is driven. Upon further rotation of the drum 1, the same will be permitted to move over the spading elei nents engaged with the soil and then as a V consequence, the said elements will be caused to become disengaged from the soil, thereby the spading elements subsequent to their en- :gagement with the soil rest upon "the pe- 106 throwing the soilaupward-and backward and a preventing. undue straining of the spading riphery of the drum 1 during the upward movement thereof. However, up gn downward movement of the same, they drop forward by gravity and assume pQSitiOns as shown in Fig; l; the spring buffers servies es 159R maintaini min sPiQfiQl relation and also absorbin all shock incident to the relative adjustment as" the el'enents.

is to be also noted, that inasmuch as the rotary s'pad'er is mounted uponthe drit e e sivi he m er dr v n r l M, he e see s, 9' t e, me ma b B as s w l serve a t a t n me s 51 fe 'v' de, dr v nsfihs same er the surf fi Pf s'oilfto'be cultivated thereby.
